I’ve used 1.1.0 on two projects so far and have been very happy with it. It seems more stable. I still have a couple issues with Android browsers, but that is more a problem with Android than jQuery. For instance, the fixed toolbars do not work reliably with Android 2.2. But jQuery said this would happen in their documentation, so it’s not a surprise. They have done a good job deprecating the feature for non-compatible browsers. Their was a small issue where the loading gif was not working correctly, but jQuery is working on the fix and it will probably be fixed by the time you read this.

All in all. I’ve been very happy with jQuery mobile 1.1.0.

Looking forward, they are improving ThemeRoller and creating a downloader for custom jQuery mobile builds that only include the items that you use in your website/app.
